Amazon Mechanical Turk

Crowdsourcing marketplace for on-demand microtasks and data annotation

Visit mturk.com ↗

Amazon Mechanical Turk (MTurk) connects businesses and researchers with a global workforce to complete tasks that humans do better than computers. Requesters post microtasks called Human Intelligence Tasks (HITs), such as data validation, transcription, and survey participation, while workers complete them for set payouts.

What it's for

  • Annotate and label images or text for machine learning datasets
  • Collect survey responses for academic or consumer research
  • Clean and deduplicate large business data records
  • Moderate user-generated content and social media submissions
  • Earn micro-payments online by completing small human intelligence tasks

Features

  • Human Intelligence Tasks (HITs) infrastructure for splitting projects into microtasks
  • Developer API for programmatically submitting tasks and retrieving results
  • Worker qualification filters to target specific demographics or skill levels
  • Pay-per-task pricing structure for scalable workforce management
  • Dedicated interfaces for requesters creating jobs and workers completing tasks

Pricing

Paid. Requesters pay set reward per task plus Amazon service fees; workers are paid per approved task.
